To all whom it may concern} i I I Be itknown that I, FRANK RoeERs,

Ba-ltim'orecity and StateofMaryland, have invented and discovered certain new ;an

useful Improvements in. f1ension Devices for Loom-Shuttles, of which the following a is a specification.

1 -My said invention relatesitoitension dievices for loom shuttles, and consists in the combinations, and-arrangements of elements hereinafter described and particularly set forth in the accompanying claims.

The invention has for its purpose qwherein the adjusting member will not bev under the blows; which'tlie shuttle receives;

come loose and project ,beyond the. surface of the shuttle and therebygcut the 'warp threads as the shuttle passes. through the shed. 1

/ The invention itsfurther u p;

to provide a device of this characten'fwhich will prolong the life of the shuttle, and wherein the tension regulating member is constructed to securely ;hold in "set position (The inyenti'on is disclosed- W y of illUstra iQn: fin the v accompa mg Whereinfe I Figure 1 1s a the tensioni ng device v applied thereto.

i ,Fig. 3 is a detall view, in section, ofamodified form of tension regulator; Referring to the construction. infurther detail, and wherein like reference characters designate corresponding parts in the difierent views shown, 4 designates a shuttle of well known type provided with a tension'device involving a lever 5 pivotally mounted on the pin 6 secured to the shuttle, and having the parts 7 thereQfpressing against the yarn and guide members 8 and 9 direct the yarn through the opening B in the bobbin after the usual manner. The above described featuresof the shuttle 'forin no part of the present invention, but are illustrated only to show the application of the tension adjusting device. I q The tension device adjusting means consists of a bushing 10' that is screw threaded to pro vlde adev1ce for regulating the tension on r w n s;

within aperture C inthe shuttle, and is formed with a head or flange 11 that fits within a -countersink 12 of the opening C,

as shown. The head 11 is'formed with a notch 12 to receive a screw driver or other like implement for applying the bushing or socket piece 10 into placefand' in thus applying the [piece the same is inserted through the opening D ith which the shuttlesareusually provided.

A screw 13 is threaded into the socket piece 10, and has a relatively large head 'or' screw 13 will tension the lever 5through said spring 15;"

Thescrew13 is or slotted, as at 1 longitudinally of its aXis and spread slightly whereby to obtain a strong frictional grip between the threads of the screw and the internal threads of'the socket pie'celO, as will be understood; The

slot 17 also serves tof receive a screw driver or'other device for turning the screw to regulate the tension" on the spring 15. The head 14 of the screw is preferably formed befa'pplie'd to the'bushing 1O through the for applying said bushing.

j; The :screw 13 will readily hold'qin the socket piece 10', and should it become loosened from anyeausethe threaded end of the screw will not project'beyond-the surgreferably a split-screw,

i fore, be seen; that any adjustment on the face 'of the shuttlewith'the disastrous results noted, since the head of screw-wi-llcon'- tact with the inner end of the bushing 10.

Any fine adjustment desired on the yarn en:

gaging lever end 7 may be obtained byinserting a screw driver or othertool' into the the shuttle.

In the construction shown in Fig. 3 the screw 13 is provided with a central projecting portion 18 that serves to receive the coil of the spring 15 that engages with the head and thereby center the spring and hold the same against lateral displacement: The projecting portion 18 is formed with a notch 19 to receive an impleof construction herein shc'wn and de scribed.
